C- elemination or reduction Method of elimination or reduction Adding two equations is to obtain a new equation whose right (left) member is the sum of the right (left) members of the equations that are added together. 7X+5y=19 -7X-2y=-16. Adding two equations 3y=3 ---> y=1 then 7x+5(1)=19 7x=19-5 x=14/7=2
